| Abstract: | Taking Chang 7 member of triassic Yanchang formation as research object, types and characteristics of sediment microfacies in Xiasiwan oil field were analyzed based on logging data through core observation and well log analysis by the newest sedimentology method. The results show that Chang7 formation in the area is composed of lake, deep lake has large-scale development in turbidite fan. The Chang7 sedimentary system controls the distribution of the oil reservoirs, source rock and cap rock. The turbidite sands in the deep lake provide quality reservoirs for oil and gas reservoir-forming. |
